Living on Dialysis: How Long Can You Survive?

I. Introduction

When someone experiences kidney failure, dialysis is often the only option to keep them alive. But how long can someone live on dialysis? This is an important question not only for patients and their loved ones, but also for healthcare providers and policy makers. In this article, we explore the medical perspective on dialysis, real-life experiences of patients, lifestyle recommendations for patients and caregivers, controversies and debates, and more.

II. A Medical Perspective

Dialysis is a medical treatment that filters waste and excess fluid from the blood when the kidneys are no longer able to accomplish this on their own. There are two main types of dialysis:

Hemodialysis: In hemodialysis, the patient’s blood is removed from their body, filtered through a machine, and then returned to their body. This may be done in a hospital or dialysis center, typically three times a week.
Peritoneal dialysis: In peritoneal dialysis, the patient’s abdominal cavity is filled with a special fluid through a catheter. The fluid draws waste and excess fluid from the blood into the abdomen, where it can then be removed. This may be done at home, daily.

Dialysis does not replace the function of the kidneys, but it can help sustain life by removing the harmful waste products from the blood.

According to the National Kidney Foundation, the average life expectancy on dialysis is 5-10 years. However, this can vary depending on a variety of factors such as age, overall health, and other medical conditions.

III. Personal Experiences

Living on dialysis can present many challenges, and each patient’s experience will be unique to their situation. Here are some examples of real-life experiences:

Case 1: Susan is a 50-year-old woman who has been on hemodialysis 3 times a week for the past 3 years. She was otherwise healthy when she was diagnosed with kidney failure. Though she finds dialysis exhausting, she is grateful for the treatment, as it has allowed her to continue to work and spend time with her family.
Case 2: John is a 75-year-old man who has been on peritoneal dialysis at home for the past 2 years. He has other health problems (heart disease, diabetes, and arthritis), which makes his dialysis treatments more difficult. He has hired a nurse to help with his treatment and finds following a strict regimen tiring.

IV. Comparing Types of Dialysis

While both types of dialysis can sustain life, they have some differences that may impact life expectancy. For example:

Hemodialysis: Patients receiving hemodialysis may be at higher risk for infections since they are connected to a machine that frequently draws and returns blood. Hemodialysis requires a reliable access to a blood vessel (called a fistula). For some patients, fistula placement may not be possible due to vein or artery blockage.
Peritoneal dialysis: Patients on peritoneal dialysis may be at risk of developing infections from the catheter that is inserted into their abdomen. Patients need to be willing to follow sterile techniques to reduce the risk of infection. Patients who have severe respiratory disease, certain abdominal conditions, or who are unable/unwilling to perform the required self-care tasks are not good candidates for peritoneal dialysis.

What type of dialysis is right for the patient will depend on many factors, such as their overall health, their lifestyle, their living arrangements, and their preferences.

V. Lifestyle Recommendations

While dialysis is critical for maintaining life, there are some changes that a patient can make to improve their quality of life on dialysis and potentially extend their life expectancy:

Diet: Following a healthy diet for kidney disease can help reduce waste products in the blood. Patients may be asked to restrict foods high in sodium, potassium, and phosphorus.
Exercise: While exercise may need to be modified depending on the patient’s specific health status, being physically active can improve overall health and well-being.
Medication: Patients can work with their healthcare provider to manage medications for other health problems, such as diabetes or high blood pressure, which can impact overall kidney function.
Managing side effects: Some patients may experience fatigue, nausea, or other side effects of dialysis. Working with healthcare providers to manage these symptoms can help with overall quality of life.

VI. Advice for Caretakers

Caring for someone on dialysis can also present many challenges. Here are some tips for caregivers:

Stay organized: Create a schedule to ensure patients make all of their appointments. Keep track of medications, dialysis supplies, and any appointments outside of dialysis.
Help with self-care: Familiarize yourself with the patient’s dialysis treatment, and help them wash and dress for dialysis.
Address emotional needs: Patients may experience depression or anxiety related to living with a chronic illness. Encourage them to talk to friends and family members, and consider seeking help from a mental health professional.

VII. Controversies and Debates

Decisions about dialysis may be difficult, particularly when it comes to end-of-life care. Some debates in this area include:

Is dialysis always the best option? Some healthcare providers may suggest that long-term dialysis may not improve the quality of life for some patients. Factors such as overall health and age may be considered when weighing the benefits and drawbacks.
How long should someone stay on dialysis? While dialysis can help extend life, it may not always be the best option for the patient. Some may decide to stop dialysis treatment once they reach a point where it’s no longer improving their quality of life.

Patients, caregivers, and healthcare providers may benefit from having open and honest conversations about the risks and benefits of dialysis as well as end-of-life care planning.

VIII. Conclusion

Living on dialysis presents many challenges, but it is possible to improve quality of life and extend the length of time someone can survive. Working with healthcare providers to optimize care and make healthy lifestyle changes can help. Caretakers can also play an important role in providing emotional and practical support. By having open and honest conversations about dialysis and end-of-life care, patients and caregivers can make informed decisions.

If you or a loved one is living with kidney disease and dialysis, there are many resources available to help. Don’t hesitate to talk to your healthcare provider or seek out a support group.
